When I started using email in the 1990s, I was advised that plain-text email was no more private than sending a postcard: most likely, nobody besides the intended recipient would bother to read it, but a number of people in theory could read it.

But on the other hand, neither did I expect to learn that the U.S. government is collecting, analyzing, reading our email. Even though I might have assumed they could do that, it's alarming to discover that they are doing that.
